Application filed June 16, 1915. Serial No. 34AM.

dent of the city of New York, borough of Manhattan, in the county of New York and State of New Y rk, have invented a new and Improved C-ha'nge-lilaking Machine, of which the following is a full, clear, and exact description.

This invention relates to coin handling devices and has particular reference to means whereby a cashier may by simple and easily operated mechanism deliver to a purchaser or a customer the necessary change wncn a purchase .is made and a sum of money in excess of the purchase price is tendered.

Among the objects of the invention, more definitely stated, is to provide a casing of suitable size provided with reservoirs or chambers for coins of as many different denominations, each chamber having associated with it a plunger movablesubstantially at a right angle to the aXis thereof whereby,

upon manipulation of the plunger, a single coin will be delivered from such chamber and all of the coins from any of the chambers whose plungers are manipulated will fall or roll into a single pocket for convenience of delivery to the customer.-

A further object of the invention is to provide means to indicate to the cashier the fact that any of the chambers are empty and thus prevent the possibility of delivering an inaccurate amount of change to a customer.

A; still further object of to provide in a device set forth means whereby each of the plungersis required to be forced to its full distance before it will return automatically to the invention is its normal position, and whereby the loclc. ing of the plunger mechanism from'proper operation is prevented and whereby turthermore the several chambers or magazines are left free to be lifted bodily upwardly out of normal position'for filling, emptying orother purposes. 7

With the foregoing and other objects in view, the invention consists in the arrange-- ment and combination of parts hereinafter described and claimed, and while the invention is not restricted to the exact details of construction disclosed herein, still for the.

purpose of illustrating a practical-embodiment thereof reference is had to the accomof the nature above panying drawings, in which like reference characters designate the same parts in the several views, and in. which- Fig'ure 1 is a perspective view showing a preferred. embodiment of the invention; F 2 is a horizontal sectional view on the line 2--2 of Fig. Fig. 3 is a vertical transverse section on the line 33 of Fig. 2;

Fig. 4 is a horizontal sectional view on a plane below the plane of Fig. 2 and indicated by the broken line 4- of Fig. 3; Fig. is a front elevation of one of the coin magazines detached and a portion of which is shown broken away on. the line 5 5 of Fig. 6; Fig. 6 is a vertical. sectional detail on the line 6-6 of Fig. 5; and Fig. 'i' is a vertical sectional detail on the line 7-7 of :Flg; i 1

As shown by the drawings the apparatus comprises a casing of substantial construction adapted .to be supported upon a. showcase, cashiers desk or the like, and having any suitable form or arrangement ,of doors, lids or drawers for gaining access to the interior thereof. To this end'the casing is shown as having a top cover or lid 11 hinged at 12 along the upper rear edge of the easing and adapted to be locked shut in. con-- nection with a front vertical panel 13 by any suitable means indicated as a hasp 14. I also provide a door 15- of cylindrical curvature hinged at 16 to the lower edge of the panel '13 and adapted to be locked closed, in connection with a horizontal plate or ledge 17.

Within the casing and preferably closely below the plate 17 is a base plate 18, the same extending rearwardly toward the back panel 19 and directly beneath the front portion of the top panel or lid 11. The base 18 constitutes the main support for the operating portions of the mechanism and may be secured in fixed rigid position by suitable means as by being connected to the rigid vertical end and front .panels 20 and 21 respectively. T1G door 15 is provided with a, transparency 15 wnereby the cashier may observe the condition of the magazines five of these magazines adapted for pennies, nickels, dimes, quarters and half dollars respectively. It, of course, will be understood that the number of these magazines may be greater or less according to the requirements of any particular business.

At the front of each magazine is provided a vertical slot 23 whereby the number of coins therein may be seen, and on opposite sides of such slot are preferably provided graduations 2 land 25, the former indicat ing the number of coins and the latter showing the monetary value of the same according to the denominations. The bottom of each magazine is closed in any suitable manner as, for instance, by a plug 26 screwed into the lower end of the tubular structure, and having a stud 27 rectangular in cross section adapted to project downwardly into and through a hole 28 inthe base'lS, whereby the magazine is held in fixed position and prevented from becoming inclined or retated around its axis, although allowing it free to be lifted verticallv out of the casing when the lid is open tor the purpose at emptying the magazine, refilling it, or making an inspection of the lower portion thereof,

The coins for each magazine are adapted to fit substantially closely or loosely in the same in a pile one above another, the lower-'. most coin resting flatly upon the upper surface of the plug 26. The lower endofthe magazine is formed with a horizontal slot 30 at its rear approximately of a semicircue lar form or equal to the internal diameter of the tube extending across the rear portion thereof on a level substantially flush with the upper surface of the. plug. Likewise a slot 81 is formed at the front of the magazinc and in the same plane as the other slot which is understood be the plane of the lowermost coin in the magazine. The. slot 31, however, is of smaller ari than the rear slot and is adapted to rose-1% I the end or blade 32 of a plunger 33 rejecting for- \vardly in a horizontal direction beyond the front of the casing and provided with a button or linger piece 3% bearing preferably a mark indicating the denomination to which the plunger pertains. Eachplunger is guided along the space'between the ledge 17 and the base 18 by means of spacing blocks 35 secured, as shown in Fig. 2, to the upper surface, of the base 18 and also by means of the front panel 21 in which are formed a series of notches 3G in which the plungers 33 are guided. The extreme end of each of the blades 32 is adapted to lie normally outside of the. slot 3 but when the plunger is pushed, will enter freely into and. through the. slot Ill and engage squarely against the lowermost coin, causing it to be ejected rearardly through the slot 30, the next upper coin being held lrom contact with the portion of the magazine directly above the slot 30. lVhen the plunger, however, is re turned to its normal position, the position indicated in Fig. :l, by any suitable automatic means such as a spring 37, the bulk of coins will drop. :40 long as there are any coins in the magazine, one of them will lie in the plane of the slots 31') and Al ready to be ejected by a subsequent manipulation of the plunger. The spring 37 connected at one end atZlS to the casing and at its other end at 39 to :1 lug projecting downwardly from the plunger Eli-l through a slot l0 formed in the base 18.

Each coin ejected is adapted to drop into a chute ll leading downwardly and outwardly in any suitable direction into a pocket or cup 42 shown in this instance as being secured at the l'ront of the casing within reach of the cashier. Each cl rs through the casing wall in a slei, l .hlhc chute reg Ling end ol the chute is prc it out ore on one side than on indicated in Fig. '1", so as to male blc coin to drop and brid across it. l this means the coin to turn on edge or in a vertical plane in a position to roll down and freely (all: at the chute. 1

. hen av purchase is made requiring change, and assuming that the amount oi? change to be given the customer is thirty-live cents,-the cashier will simply force the plungers marked 10 and rcarwardly so :is to eject a dime and a quarter, which coins will roll promptly into the pocket -12. It the amount of change required should necessitate the actuation of the same plunger a phe rality of times, such ac ation may be done very rapidly and the coins will :nzcordinglv be ejected in rapid succession, all rolling down the same chute to the same point of delivery.

This device being adapted especially lol use where change nus't be made rapidly. and

, even though the cashier may at any time. b

taking notice, obser 'e the condition ol the supply of the coins with respect to their magazines, yet it is desirable at times to pro vent the actuation of the plungers when the magazines should happen to be empty. More definitely stated, should the p -t l'i be arr: nged at the rear or end of the ring. whereby the customer may recei e dirccily his own change therefrom, should any of the magazines be empty and hence fail I..- deliver, a controversy between the cuslmzu-r and the cashier might arise to the embarrassment oi' the latter. 1' therefore provide an automatic locking device in cimnection with each magazine which prevents the operation of the-plunger when such magazine isrmpty. Such locking device therefore constitutes .an indicator innnediatcly aplOO lllll lilii front end of thedog' is enlarged or bent upprising the cashier that such magazine is empty, and the cashier will be governed ac- The automatic lock provided cordingly. I for this purpose comprises a dog 44: pivoted at 45 intermediate its ends transversely of the groove 29 formed in the plug 26. The

wardly forming a stop 44 and lying directly in the rear of the slot 31 when the magazine is empty, the dog being swung on its pivot in such position-by gravity acting downwardly upon the weighted rear end 46, as shown in Fig. 6. When, however, one or more coins are in the magazine, the, dog will be held by the lowermost coin so as not to obstruct the passage of the plunger blade as above described. The dog may be madestrong enough for its purpose to prevent the movement of the plunger and yet may be sufficiently delicately pivoted to insure that a single coin in the magazine will hold it down out of locking position, as shown in Fig. 3.

To insure that each plunger will be given a full stroke at each operation so as to cause the coin to beentirely ejected, I provide a pawl 47 pivoted freely upon the plunger and cooperating with a rack 48 fixed beneath the slot 40, the pawl47 is slightly longer.

than the vertical distance between its pivot and the rack and is adapted to swing free i from the rack at each end of the stroke of the plunger. WVhen the plunger is given its action stroke to eject the coin, the pawl drags idly over the teeth of the rack, and when the stroke is completed it will drop beyond the rear end of the rack and hence will drag idly over the rack on the automatic return stroke of the plunger. If, however, the stroke is too short to eject a coin, the pawl will not have left the rack, and being in an inclined position, will automatically lock the plunger from return under the force of the spring 37. Another impulse upon the plunger, therefore, will be required to eject the needed coin.

The lid 11 may be fitted with any suitable size or form of funnel devices to guide the several denominations ofcoins into their respective magazines, such devices being indicated at 49; Under ordinary conditions, therefore, the cashler will place the coins received from the customers directly into the hoppers 49 where they will fall into proper position in the several magazines. Should, however, any of the magazines become full or the cashier be too busy to assort the coins i for'this purpose, they may be laid temporarily on the ledge 17 or in any'other convenient position... f Currency and other matter .than coins may be placed inboxes or drawers indicated at 50 or in any other Copies of this patent may be obtained for unoccupied portion of the casing, held shut by a catch 51 and adapted to be projected when the catches are released by a spring 52. The catch may be released by a button 53 shown best in Fig. l. L

I claim: j 1. ln a change-maklng machine, the combination of a casing, a substantially flat horizontal base secured within the casing' and provided with a series of rectangular sockets, a series of coin magazines having closed bottoms provided w1th rectangular lugs projecting freely downwardly into the respective sockets, thereby holding the magazines from tilting or rotation, said magazine bottoms being provided with front and v rear slots, and means acting through one of said slots to project a coin through the other of said slots with respect to each magazine.

2. In a change making machine, the combination of'a casing, a series of vertically arranged coin magazines supported in the casing and removable freely therefrom independently of one another through the top of the casing, each magazine having a solid closed bottom provided with a groove extending longitudinally therein fromk front to rear leaving coin supporting shoulders on opposite sides of the groove, said maga-;

zine also having front and rear slots arranged in the same plane as the shoulders aforesaid, means normally arranged outside of the magazine but acting through the front slot to eject a coin through the rear slot, and movable means mounted within the magazine-in said groove and serving automatically when the magazine is empty to prevent the operation of the coin ejecting means, said movable means being removable with the magazine.

= 3. In a device of the character set forth, the combination of a vertically disposed and vertically removable magazine of tubular form and having at its lower end front and rear slots arranged in the same horizontal plane, a solidsupporting plug secured in the lower end of the magazine and having 1ts upper end lying in the same plane as said slots, said plug being provided with a groove in its upper face extending below the plane of the slots and from one slot to the other,

a dog pivoted intermediate its ends transversely of the groove, said dog having at its front end a stop projecting upwardly and serving to close the front slot. when -the magazine is empty, said stop being held normally out of stop position by the'lowermost magazine is occupied.
